Inquiry about Natural Lava Stone Diffuser Bracelets NEW

I am looking for a manufacturer of natural lava stone diffuser bracelets. The lava stone must be genuine, porous, and able to absorb fragrance oils. I need elegant, minimalist designs for both men and women, with stainless steel components (preferably 316L), no elastic, metal chain or wire construction, secure clasp, and adjustable length. I am also interested in models that combine black lava with accent stones like dark blue, brown, or amber. Each bracelet should include a small metal plaque for engraving a simple "V" logo. Please send photos and videos of your existing matching models. I would like to start with a test order of 10–30 pieces, with potential for larger orders up to 500+ pieces. Provide pricing for 10/20/50/100 pieces, MOQ, sample cost, shipping to Poland, engraving options, and production time. I seek a long-term partner.
